Patented Jan. 9,1912.

Application filed .Tune 1, 1911. Serial No. 630,559.

To all whom may concern Be it known that L CHRISTIAN P. CHRES- TENsnN, a subject ofthe King of Great Britain, residing at Philadelphia, in the county of Philadelphia and State'of'Penn- Sylvania, have invented certain new and useful Improvements in fapenCutters, of which the following is a specification.

lily invention relates to improvements .in paper cutters, I device vof this character' designed for trimming the edges of wall paper and the like, the'object a simple inexpensive hand operative device of this character which will'accurately cut a strip the desired the paper, and which may be quickly and easily yoperated so as to save time and more accurately trim the paper than has.' been done heretofore. y

With these and other objects in view, the invention consists' in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

ln. the accompanying drawings:v Figure 1, is a plan. view illustrating my improvements. Fig. 2, i sa view in elevation at right angles to Fig. 1. Fig. 3, is an end elevation, and Fig. il, is a view in section on the line of l. y

1, represents a paper guide which 1s composed of sheet metal bent upon a longitudinal line so 'as to provide two leaves 2 and 3 to receive the paper between them on fold line constituting a straight edge so asjto lguide the cutter. .it will be noted that one of the leaves 3 protects outward beyond the other lea-f 2, and this structure renders it easy to insert the paper between the leaves.

is a slwet metal strip bent between its ends, and its ends overlapping the guide 2, and soldered or otherwise secured to the latter. This strip 5 provides a laterally projecting memberV on the guide, between the sections of which springs and 7 are secured by rivet 8, for a purpose which will hereinafter appear. l

9, 9, represent parallel rods which are held inparallelism by means of bars'lO,

and 1l, 'he former having a fixed relation to the rods and secured by nuts 12, and the latter adjustable on the rods. and secured and more particularly to a of .the invention being to provide width from the edge ofy lcomprising at any adjustment by means' of afthumb screw 13. The free ends of the rods 9 are reduced 1n .diameter forming. journals'lt,

lon which cutting rolls 15 are mounted and held by means of nuts 16 screwed onto the threaded ends'of the journals. These cutting rolls 15 are beveled, and one ofthe rods 9.is longer than the other so as to `permit the cutting face of one roll-to overlap the cutting .face of the ot-her, so 'that the.

rolls serveto cut as will be hereinafter explamed.-

The upper guide 2 is removably connected to the rods 9 by means ofthe springs 6' and 7 above referred to. The spring 7 is bent downwardly, and is provided with a hooked end 17 to engage underA the. lower rod 9, while the spring 6 is composed of two members 18, 18, which are straddled apart at their free ends and bowed outward at a point removed from their free ends, as illustrated at 1 9, the outwardly straddled portions 18 constituting an entrance for the upper rod 9, and the bowed out portions 19a clamp, to .clamp the rod. 'By means of these springs, the paper guide may be readily attached to or detached from the rods, and it may be.- moved along the rods as far as permitted bythe bar 11, which latter regulates the width of the strip cut from the paper.

In operation, the paper to be cutA is inserted in the 'guide 1, and the latter moved along the paper, or ther paper through the uide, and between the cutting rolls 15,

'which latter smoothly cut the strip from the paper.

Various slight changes might be made in the general form ,and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, 4but consider myself atv vliberty to make such changes and alterations as fairly fall within the spirit and scope .of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

"1. A device of the 'character described,

a paperfguide, parallel rods located at right angles to the guide, cutting rolls on said rods, a laterally projecting extension on saidguide, a spring hook secured to said extension, 'andadapted to engage one of said rods, and a double spring also I tially as..,de`scribed.

seered rosaid extension-and adapted. to clamp the other of 'said guides, 'substan he .chractler described, comprising@J paper guide, parallel' rods -lo.

'2. Aidevice of cated ai right angles-- the'guide, cutting lrollsy on said rods, a laterallyprojecting'ex- 'tension' on said guide, a, .spring hook secured to said extension, and adapted to engageone of-*said rodsya double spriii also-'se- -said bar' iginst Ir-iovenient on the .'ro'ds, and Y. vsaid .double` spring bearingagainst'said barv 15' .whereby -the position 'of the bar regulates the Width of the strip but;siibsent'ially' 'as described. In testimony whereof I have signed my name to this 'speciicetioiiA 11i tne. presence y() of'two subscribing witnesses.
